My periods are usually abnormal but for the past 3 months they have been normal. I do have a boyfriend and we do have unprotected sex, but he never ejaculates in me. I missed my period last week and yesterday when I woke up i had brown discharge. Its normal to have that after a period its just the remaining dried blood, but i don't know why it had occured since I missed my period. There jus a tiny bit today but hardly anything. I did take a home pregnacy test yesterday and it came back negative. So I don't know what is happening. There is no smell or any irrataion. Any advice, or answers would be very helpful. Also I'm 19.
